Title: Forging method of tube plate
Inventor: KOMADA SUSUMU
IPC: B21J5/00
Filed: 1979-11-16
Abstract: PURPOSE: To form a projected hub easily on the periphery of both sides of a disk by installing a rotating table to a tongue of a manipulator and placing it vertically between upper and lower anvils and pressing a blank by holding and rotating it with  the rotating table.  
     CONSTITUTION: Fittings 2 for a rotating table are fixed to a pair of manipulator tongues 1 with pins 3, and the rotating table 9 is installed to a front board 4 of the fittings 2 for the rotation table to allow rotation. The rotation table 9 has a diameter that corresponds to the diameter of the central plate of a forged product. A disk-shaped blank (m) is held by the rotation plate 9 so that it becomes perpendicular to upper and lower anvils. The disk-shaped blank (m) is pressed using upper and lower anvils. At the same time, the manipulator is moved forward and backward, and the disk-shaped blank (m) is brought into contact with the lower anvil  by its movement in one direction, and intermittent rotation of the blank in a fixed direction is caused by friction. The periphery of the blank (m) protruded from the rotating table 9 forms a hub around the rotating table 9 successively, and a forged product of specified shape and dimension is formed.

Title: Sequential continuous casting method for dissimilar kinds of steel
Inventor: MATSUKAWA TOSHITANE
IPC: B22D11/12
Filed: 1981-09-25
Abstract: PURPOSE:To improve yield without giving any adverse influence upon the quality of an  ingot in a titled method wherein coolants which settle by gravity into a mold and are  used as partition walls by rolling down the succeeding end part of the ingot of the  previous steel kind in the state of having an unsolidified layer internally. CONSTITUTION:In a method for charging coolants 4 at the end of casting of a previous  steel kind 6 and continuing the casting of a succeeding dissimilar steel kind 7, the arbitrary length part in the succeeding end part of the ingot 6 is rolled down with pinch  rolls 9 in the state of having an unsolidified layer internally. Then the volume of  shrinkage cavities 5 is decreased by as much as the volume in the unsolidified steel  part is decreased, and a required discarding part is shortened considerably. This rolling  down treatment has not only the effect of decreasing the length of the cavities 5 but  the effect of improving yield unless the treatment is carried out in the state of having  the layer 3 in the ingot. The position and range where the rolling down treatment is  applied are easily controlled by measuring the casting length from the point of the  time when the coolants are charged, with an exisiting measuring machine for the length of the ingot.
